Health experts from WHO and the CDC have said containment of the flu is no longer a feasible option, according to the New York Times. The focus has now shifted towards mitigation. Although there has been talk of closing borders, epidemiologists have said it would only be marginally beneficial. Doing so would put a large strain on healthcare facilities since most masks, gowns and gloves, electrical circuits for ventilators and communications gear, and pharmaceutical drugs and the raw materials to make them are imported from many other countries, said Dr. Michael T. Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.
